1. Isingeniso kuma-Cryogenic Valves
Ama-valve e-Cryogenicama-valve aklanywe ngokukhethekile asetshenziselwa ukulawula ukugeleza koketshezi namagesi abandayo kakhulu, ngokuvamile emazingeni okushisa angaphansi kwalawa-40°C (-40°F)Lawa ma-valve abalulekile ekuphatheni izimboniigesi yemvelo encibilikisiwe (i-LNG), i-nitrogen ewuketshezi, umoya-mpilo, i-hydrogen, kanye ne-helium, lapho ama-valve ajwayelekile engahluleka khona ngenxa yokucindezeleka kokushisa, ukuphuka kwezinto, noma ukwehluleka kokuvala.
Ukuqinisekisa ukusebenza okuphephile nokusebenza kahle, ama-valve e-cryogenic aklanywe ngezinto ezihlukile, iziqu ezinde, kanye nezindlela ezikhethekile zokuvala ukuze amelane namazinga okushisa aphansi kakhulu ngaphandle kokuvuza noma ukwehluleka kwemishini.
2. Izici Eziyinhloko Zesakhiwo Sama-Cryogenic Valves
Ngokungafani nama-valve avamile, ama-valve e-cryogenic afaka izakhi ezithile zokuklama ukuze abhekane nokubanda okukhulu:
2.1 I-Bonnet Enwetshiwe (Isandiso Sesiqu)
- Kuvimbela ukudluliselwa kokushisa kusuka endaweni ezungezile kuya emzimbeni wevalvu, kunciphisa ukwakheka kweqhwa.
- Igcina ukupakisha kanye ne-actuator kusezingeni lokushisa elifanele ukuqinisekisa ukusebenza kahle.
2.2 Izinto Zokuvala Ezikhethekile
- UkusetshenziswaI-PTFE (Teflon), i-graphite, noma izimbozo zensimbiukugcina ukuvalwa okuqinile ngisho noma amazinga okushisa e-cryogenic.
- Kuvimbela ukuvuza, okubaluleke kakhulu kumagesi ayingozi njenge-LNG noma i-oxygen ewuketshezi.
2.3 Izinto Zomzimba Eziqinile
- Kwenziwe kusukelainsimbi engagqwali (SS316, SS304L), ithusi, noma i-nickel alloysukumelana nokubuthakathaka.
- Amanye ama-valve e-cryogenic asebenzisa umfutho ophezuluinsimbi eyenziwe ngobumbaukuze uthole amandla engeziwe.
2.4 Ukufakwa Kwe-Vacuum (Ongakukhetha Uma Ubanda Kakhulu)
- Amanye ama-valve aneziciamajakethi e-vacuum anezindonga ezimbiliukunciphisa ukungena kokushisa ezindaweni zokushisa eziphansi kakhulu.
3. Ukuhlukaniswa kwama-Cryogenic Valves
3.1 Ngebanga Lokushisa
| Isigaba | Ibanga Lokushisa | Izicelo |
| Amavalvu Aphansi Okushisa | -40°C kuya ku-100°C (-40°F kuya ku-148°F) | I-LPG (i-propane, i-butane) |
| Amavalvu e-Cryogenic | -100°C kuya ku--196°C (-148°F kuya ku--320°F) | I-nitrogen ewuketshezi, i-oxygen, i-argon |
| Amavalvu e-Ultra-Cryogenic | Ngaphansi kuka -196°C (-320°F) | I-hydrogen ewuketshezi, i-helium |
3.2 Ngohlobo Lwevalvu
- Amavalvu Ebhola E-Cryogenic– Kungcono kakhulu ukuvala ngokushesha; kuvame kakhulu ezinhlelweni zegesi ze-LNG nezezimboni.
- Amavalvu Esango Eliyi-Cryogenic– Isetshenziselwa ukulawula okugcwele okuvulekile/okuvaliwe ngokunciphisa ukucindezela.
- Amavalvu E-Cryogenic Globe- Nikeza ukulawulwa okunembile kokugeleza kwamapayipi e-cryogenic.
- Ama-valve Okuhlola E-Cryogenic– Vimbela ukubuyela emuva kwegesi ezinhlelweni zokushisa okuphansi.
- Amavalvu e-Cryogenic Butterfly– Ilula futhi incane, ilungele amapayipi amakhulu.
3.3 Ngesicelo
- Amavalvu e-LNG– Phatha igesi yemvelo encibilikisiwe ku--162°C (-260°F).
- Izindiza kanye Nokuvikela– Kusetshenziswa ezinhlelweni zikaphethiloli werokhethi (i-hydrogen no-oxygen oketshezi).
- Ezokwelapha Nezesayensi– Kutholakala emishinini ye-MRI kanye nendawo yokugcina izinto ezicijile.
- Ukucutshungulwa Kwegesi Yezimboni- Isetshenziswa ezitshalweni zokuhlukanisa umoya (i-oxygen, i-nitrogen, i-argon).
4. Izinzuzo zama-Cryogenic Valves
✔Ukusebenza Okungenabufakazi Bokuvuza– Ukuvala okuthuthukisiwe kuvimbela ukuvuza kwegesi okuyingozi.
✔Ukusebenza Kahle Kokushisa– Ama-bonnet anwetshiwe kanye nokushisa kunciphisa ukudluliselwa kokushisa.
✔Ukuqina– Izinto ezisezingeni eliphezulu ziyamelana nokuqhekeka nokuqhekeka.
✔Ukuthobela Ukuphepha- ImihlanganoI-ASME, i-BS, i-ISO, kanye ne-APIizindinganiso zokusetshenziswa kwe-cryogenic.
✔Ukulungiswa Okuphansi– Yakhelwe ukuthembeka kwesikhathi eside ezimweni ezinzima.
5. Umehluko Obalulekile Phakathi Kwama-Cryogenic nama-Valve Ajwayelekile
| Isici | Amavalvu e-Cryogenic | Amavalvu Ajwayelekile |
| Ibanga Lokushisa | Ngezansi-40°C (-40°F) | Ngaphezulu-20°C (-4°F) |
| Izinto zokwakha | Insimbi engagqwali, i-nickel alloys, ithusi | Insimbi yekhabhoni, insimbi ephonswe, ipulasitiki |
| Uhlobo Lophawu | I-PTFE, i-graphite, noma izimbozo zensimbi | Irabha, i-EPDM, noma ama-elastomer ajwayelekile |
| Umklamo Wesiqu | Ibhonethi enwetshiweukuvimbela i-icing | Ubude besiqu obujwayelekile |
| Ukuhlolwa | Ukuhlolwa kobufakazi be-cryogenic (i-nitrogen ewuketshezi) | Ukuhlolwa kwengcindezi ye-Ambient |
Isiphetho
Ama-valve e-Cryogeniczibalulekile ezimbonini ezibhekene noketshezi olusezingeni eliphansi kakhulu lokushisa. Umklamo wazo okhethekile—oquketheamabhonethi anwetshiwe, izivalo ezisebenza kahle kakhulu, kanye nezinto ezihlala isikhathi eside—kuqinisekisa ukusebenza okuphephile nokusebenza kahle ezimweni ezimbi kakhulu. Ukuqonda ukuhlukaniswa kwazo, izinzuzo, kanye nomehluko kumavalvu ajwayelekile kusiza ekukhetheni ivalvu efanele yezinhlelo zokusebenza ezidinga i-cryogenic.
